Symptoms

Multimedia

The appearance of skin affected by sun allergy can vary widely, depending on the disorder that's causing the problem. Signs and symptoms may include:

Redness

Itching or pain

Tiny bumps that may merge into raised patches

Scaling, crusting or bleeding

Blisters or hives

Signs and symptoms usually occur only on skin that has been exposed to the sun and typically develop within minutes to hours after sun exposure.

When to see a doctor

See a doctor if you have unusual, bothersome skin reactions after exposure to sunlight. For severe or persistent symptoms, you may need to see a doctor who specializes in diagnosing and treating skin disorders (dermatologist).
